# Updating Your SelfServ SCO

Keep the Self Checkouts flying.


  • Duplicate your JSM | SelfCheckout V3 model and store it outside your workspace.

In case anything goes south, you will always have a restore point.

  • From the fresh copy of JSM SCO, copy the Deploy script. (Inside JSM | SelfCheckout V3)
  • In your existing installation, delete the old Deploy script, and paste in the new Deploy script.

After updating, confirm that the Self Checkouts boot and function without throwing any errors to the Console.
